Relation of the surfactant HLB parameter with the dispersion and electrical properties of residue emulsified system

The relation between the hydrophilic-lipophilic balance (HLB) parameters of surfactants and the dispersion and electrical properties of the residue emulsified system were investigated. Droplet size and droplet distribution analysis were used to evaluate dispersion properties of the emulsions prepared with emulsifier blends of different HLB values, while the conductivity was used to appraise the electrical properties. The residue was emulsified and dispersed by the mixed emulsifier. The effects of surfactant HLB parameters on the dispersion properties of brine in the residue and the electrical properties were examined. The results showed that the emulsions prepared with emulsifier of various HLB values are also different in the dispersion and electrical properties; there is a non-linear correlation between the dispersion and electrical properties and HLB value of the mixed emulsifier.
